DESCRIPTION OF THE PREFERRED EMBODIMENTS

Hereinafter, technical solution in embodiments of the utility model will be described in a clearly and fully understandable way in conjunction with accompanied drawings in embodiments of the utility model. It is obvious that the described embodiments are just a part but not all of the embodiments of the utility model. Based on the embodiments in the utility model, those ordinarily skilled in the art can obtain other embodiment(s), without any inventive work, which come(s) within the scope sought for protection by the utility model.

As shown in FIGS. 1 to 5 , a film laminator for cell phones is provided by the embodiment, and useful for film lamination on a surface of a cell phone. The film laminator for cell phones according to the embodiment includes: a cell-phone fixing plate 1 and a film laminating plate 2. A top surface of the cell-phone fixing plate 1 is a horizontal face, and in the cell-phone fixing plate, there is established a through hole for receiving a cell phone, so that edges of the cell phone fit in with sidewalls of the through hole 10. On the top surface of the cell-phone fixing plate 1, there is further provided at least one position limiting plate 11 for abutting a cell phone within the through hole 10. The position limiting plate 11 is fixed to the top surface of the fixing plate 1, and is useful for abutting a surface of the cell phone to which a film is to be attached, so as to make sure that the surface of the cell phone to which a film is to be attached lies in the same plane as the top surface of the cell-phone fixing plate 1. In general, the position limiting plate 11 serves to abut an edge of the surface of the cell phone 3 to which a film is to be attached, and as such, not only the normal film lamination is not affected, but also the surface of the cell phone to which a film is to be attached can be assured of lying in the plane on which the top surface is located. The film laminating plate 2 is useful for fixing a cell-phone film 30, one end of the film laminating plate 2 is hinged to the cell-phone fixing plate 1, and the other end of it is movable freely so that the film laminating plate 2 is bonded with the top surface of the cell-phone fixing plate 2. The position limiting plate 11 is usually two, which are generally designed to be at both sides of the through hole 10; of course, the position limiting plate 11 may also be one. In the case that one position limiting plate is adopted, the position limiting plate 11 is usually U-shaped. This can make sure that the surface of the cell phone to which a film is to be attached fully abuts the position limiting plate 11 as well.

When embodiments of the utility model are in use, because the position limiting plate 11 is provided on the cell-phone fixing plate 1, the surface of the cell phone 3 to which a film is to be attached can handily be kept in flush with the top surface of the cell-phone fixing plate 1. Upon film lamination, the film laminating plate 2 can contact with the top surface of the cell-phone fixing plate 1 and the surface of the cell phone 3 to which a film is to be attached (as shown in FIG. 4 , which is usually the screen of the cell phone 3) at the same time, so that the stress that is laid on it in the course of film lamination is very even, and bubbles are not liable to occur. Thus, a good effect of film lamination is obtained. Embodiments of the utility model are especially adaptable for sticking hard cell-phone thin films, such as glass films, thin films of toughened glass, sapphire films, or the like. As the top surface of the cell-phone fixing plate 1 lies in the same plane as the surface of the cell phone 3 to which a film is to be attached, when a hard thin film is stuck on, there is no such case where it is splintered due to uneven stress laid on it. Thus, the sticking quality is guaranteed. Furthermore, as the film laminating plate 2 is hinged to the cell-phone fixing plate 1, and a precise corresponding relationship between the cell-phone film 30 and the cell phone 3 to which a film is to be attached can be obtained, the accuracy of alignment of the laminated film is guaranteed.

On the basis of the above embodiment, a hanging hole 15 is further provided on the cell-phone fixing plate 1 in the embodiment. The hanging hole 15 is generally located at a terminal of the cell-phone fixing plate 1, and is usually in a long strip shape. A notch may also be provided on a side wall of the hanging hole 15, so that the cell-phone fixing plate 2 is kept in balance in a state of hanging.

On the basis of the above embodiment, two sets of positioning holes 12 are provided on the cell-phone fixing plate 1; the position limiting plate 11 is two, each of which is fixed onto the cell-phone fixing plate 1 by means of a set of positioning holes 12. With the design of positioning holes 12, position fixing accuracy of fixing the position limiting plate 11 onto the cell-phone fixing plate 1 can be assured, and a good contact is also guaranteed when a bottom surface of the position limiting plate abuts the surface of the cell phone 3 to which a film is to be attached. As shown in FIG. 2 , preferably, in the case that two position limiting plates 11 are adopted, each of the position limiting plates 11 is located at an edge of the through hole 10, and each of the position limiting plates 11 covers a part of the through hole 10. As can be seen from FIG. 3 , each of the position limiting plate 11 goes beyond an edge of the through hole 10 approximately by 1 to 3 mm, so that an edge of the cell phone 3 abuts well against the position limiting plate 11 and the region for film lamination is not affected.

On the basis of the above embodiment, further, a groove 20 for fixing the cell-phone film 30 is provided on the film laminating plate 2, and is established on a face of the film laminating plate 2 for bonding with the cell-phone fixing plate 1. In general, when the film laminating plate 2 is bonded with the top surface of the cell-phone fixing plate 1, the groove 20 coincides with the through hole 10. Especially when the cell-phone film is stuck on the cell phone screen, the groove 20 and the through hole 10 are substantially equal in area. Of course, when the film is attached to the cell phone screen, the shape of the through hole 10 is the same as the shape of profile of the cell phone 3, so that the cell phone 3 is firmly clamped within the through hole 10 on the cell-phone fixing plate 1.

On the basis of the above embodiment, further, the cell-phone film 30 includes a first outer film, a primary film and a second outer film that are stacked sequentially. A separating strip (not shown in the figure) is provided at an end of the first outer film, an end of the second outer film is jointed to the film laminating plate, and an adhering sheet is arranged between the first outer film and the primary film.

As shown in FIG. 5 , after the cell-phone film 30 is fixed onto the film laminating plate 2, the first outer film is torn off by the aid of the separating strip, and the film laminating plate 2 is bonded with the top surface of the cell-phone fixing plate 1 after it has passed through three positions of A, B and C in sequence, so that the primary film is stuck on a surface of the cell phone 3 to which a film is to be attached with the adhering sheet. Subsequent to the film sticking, open the film laminating plate 2. As the second outer film is fixed onto the film laminating plate 2, the second outer film is automatically separated from the primary film. Thus, the entire process of film lamination is completed.

On the basis of the above embodiment, further, the position limiting plate 11 is generally made of a hard plastic plate, preferably a PET board, and its thickness is in the range of 0.1 to 0.5 mm. The film laminating plate 2 is usually also made of a hard material, and for the sake of reducing the cost, is preferably a hard paper board, and its thickness is in the range of 0.5 to 1.5 mm. The cell-phone fixing plate 1 is a hard paper board, and its thickness is in the range of 2.5 to 7 mm A hard paper board is usually made of multiple levels of hard paperboard by pressing, so as to ensure a sufficient strength. Certainly, the used hard materials are each a thin plate or a sheet possessing a certain hardness, such as a plastic board, a cardboard sandwich plate, or the like.

As shown in FIG. 6 , FIG. 7 and FIG. 8 , in another embodiment of the utility model, a film laminating plate 2 is usually a transparent construct. That is, in a practical application process, a transparent plastic substance or other transparent material with a certain hardness is used for the film laminating plate 2. Because the film laminating plate 2 is a transparent construct, in the entire process of film lamination, an operator can visually inspect whether or not dust or air bubbles is/are present between a primary film and the surface of a cell phone to which a film is to be attached. Therefore, the success rate of film lamination and the quality of film lamination are improved greatly. On the basis of the above embodiment, further, an exhaust through hole 25 is established on the film laminating plate 2, and communicates with the bottom of a groove 20. The exhaust through hole 25 is generally designed to be in the center of the groove 20, and is usually in the shape of an oval or a long strip, and its size is usually subject to receptibility of a thumb. The function of the exhaust through hole 25 is not merely limited to such a function that the residual air between a cell-phone film 30 and the film laminating plate 2 can be discharged by it, but also it can facilitate the operation. As shown in FIG. 8 , after a primary film of the cell-phone film 30 is aligned with the surface of a cell phone to which a film is to be attached, an operator presses a central zone of the cell-phone film 30 via the exhaust through hole 25 so that the central zone of the cell-phone film 30 is bonded firstly. Thus, bubbles are prevented from generating in the central zone, and the operational quality is improved. It is to be noted that, when an opaque substance is used for the film laminating plate 2, the opaque substance takes priority for establishment of the exhaust through hole 25 on it over others. As such, not only the cost can be saved, but also the quality of laminated film is improved greatly.

It is to be noted that, the technical solution of the embodiment is not limited to the field of cell phones, rather, digital products such as tablet computers, digital cameras, digital music players and the like each can adopt the solution of the utility model for film lamination. Of course, the utility model is especially adapted for the sticking of a hard cell-phone film, such as, a glass film, a thin film of toughened glass, a sapphire film, or the like.
